Winch Systems & Products
There is no such thing as a standard
winch. We supply winches for
varying requirements in every field.
Deepwater deployment with winch
loads of 100 tons or more calls for a
different approach than for a diving
bell, where reliability is of utmost
importance. We offer standard and
custom made solutions to meet any
capacity with any certification.
DURABLE & RELIABLE
WHY OUR WINCHES?
- Innovative winch solutions adapted
to the latest market requirements
- Tailor made to any requirement
- Proven track record
- Installation, engineering,
manufacturing, commissioning,
in-house design and after sales
services
- Worldwide presence
- Certifications meet all standards
set forth by accredited bodies and
industry standard.

Surface diving LARS
The surface diving LARS is designed for
safe launch and recovery of surface divers.
The system is designed for easy, cost
effective transportation and is versatile
enough to be used from different locations.
The system provides an easy and reliable
two-men diving cage and can be mounted
on a skid for easy transportation.
The system consists of an integrated HPU
and control unit to operate the system.
ROV LARS
The ROV LARS is designed to move subsea
packages from ship deck to subsea and
back again. The system has been designed
for use in 4,000 m water depth with luffing
SWL of 15MT and overboard SWL of
20MT. A-Frame Docking Head Assembly
has full luffing load slewing capability of
approximately 270˚. The total system is
comprised of an over the centre A-Frame,
an Umbilical Winch with Right-Angle
Levelwind, and a dual string HPU to power
all systems.
Saturation diving LARS
The saturation diving LARS is designed for
safe launch and recovery and delivery of
the diving bell to the deck decompression
chamber. The system is designed for
easy cost effective transportation and is
versatile enough to be used in different
configurations. The system consists of a
supporting frame structure for the A-Frame
and Winches, Launch and Recovery
A-frame, Saturation Diving Guide Wire
Winch, Saturation Diving Main Bell Winch,
and HPU. Optional Powered Sheave or
Umbilical Reeler is available.
DEEPWATER DEPLOYMENT AND UTILITY WINCHES
5 MT Deep Water Hydraulic Tugger Winch
Our 5 MT Deep Water Hydraulic Tugger Winch comes standard
with dual counterbalance valves to provide dynamic braking
during pay out operations. This eliminates the need for having
a band brake directly mounted on the winch drum to act as a
dynamic brake (required for pneumatic winches). Band brakes,
specifically when used for dynamic braking, go through excessive
wear on the friction material (brake pads) and thus require
frequent replacements resulting in pulling the winch out of service
more often. The net effect of this is a decrease in overall reliability.
To achieve a line speed of 70 fpm, the pneumatic winch will
require 800 SCFM of air, any less amount provided to the winch
will slow the line speed. The hydraulic option provides twice this
speed under full load, and 3.5 times this speed under no load (i.e.
trip down).
Deepwater Soft Rope Traction Winch
In deepwater applications, as payloads get heavier using wireline
becomes unsafe and difficult to handle. To stay within industry
approved guidelines for safety something else must be used.
We can provide you with a solution to this challenge by using
Synthetic Rope in combination with our Deepwater Soft Rope
Traction Winch. Synthetics have advanced to the point where
their characteristics are similar to wire rope, but because it is
neutrally buoyant, safety margins are maintained. With the use of
synthetics, the entire handling system gets smaller.
Systems Offered

UTILITY WINCHES AND CRANE REPLACEMENT WINCHES
DIVING/ROV WINCHES
Guide Wire (Clump Weight) Winch
The Guide Wire (Clump Weight) Winch,
certified under DNV Rules for Diving
systems OS-E402, includes a 7.5MT full
drum SWL with a 80 fpm full drum speed.
The drive system consists of a bull gear
and pinions driven by large displacement
motors. The drives and brakes meet IMCA
requirements. The two brakes include
a multi-disk in motor and caliper disk,
both spring to set/pressure to release.
Even though the system is equipped with
two motors, only one is required for full
performance. The manifold motor switching
functionality eliminates the majority of
tubing plumbing. The winch consists of a
grooved (lebus type) drum liner and a self-
correcting levelwind with override. Multiple
rope exit angles as well as over- and
underwound options are accommodated.
The drum guards are standard. Minimum
design temperature: -10 °C
Crane Replacement Winches
Crane Replacement Winches are designed to replace less robust
winches currently in use in the field. They are API-2C and
ABS-CDS compliant and equipped with Dual Band Brakes, spring
set and hydraulic release. The Band Brakes come with Wear
Indicators. The Automatic Drum Lock has a spring engaged and
hydraulic release. A grooved Drum Liner (Lebus Type) is a standard
feature.
Dive Bell Winch
Our Dive Bell Winch, certified under DNV
rules for Diving systems OS-E402, consists
of a 12MT full drum SWL, with a 60 fpm
full drum speed. The bull gear and pinions
of the drive system are driven by large
displacement motors. The drives and
brakes meet IMCA requirements. The two
brakes consist of a multi-disk in motor and
caliper disk, both spring to set/pressure
to release. Even though the system is
equipped with two motors, only one is
required for full performance. The manifold
motor switching functionality eliminates
the majority of tubing plumbing. The
winch consists of a grooved (lebus type)
drum liner and a self-correcting levelwind
with override. Multiple rope exit angles
as well as over- and underwound options
are accommodated. The drum guards are
standard. Minimum design temperature:
-10 °C.
General Utility Winches
General Utility Winches come standard with a Line Speed of 0-100
fpm (full drum), Infinitely Variable. They are equipped with a Multi-
Disk Caliper Brake to hold 2X SWL. 300 psi, 40 gpm hydraulic oil
input required. Standard Controls are remote Hydraulic Piloted.
Winches are also available with Solenoid Piloted Controls.
The umbilical reeler drive system
The Umbilical Reeler drive system is
bull gear and pinion driven by a large
displacement motor. The single disk
brake / two calipers, both spring to
set / pressure to release.
The reeler is supplied with a self-
correcting levelwind with override.
Level Wind allows for multiple rope exit
angles. The drum guards are standard
(guards not shown). Minimum design
temperature: 10 °C.
